The Viking Age is in its final century. Thorfinn, a merchant ship owner, has invested heavily in an Atlantic crossing to Vinland, Adam of Bremen is seeking Ari Marrson and a monastic order, called the Culdees. Gudrid, and a band of explorers are returning to begin where they left-off twenty years earlier, a grave site at Kjalarness. Their separate quests converge, seeking an ancient city of gold.
